OK I've had a reply from Chord Electronics
"
Dear Sir, thanks for your inquiry.
With all our products, the maximium sample rate via optical is 24/96 as this is all the connection is ratified for. The other connections can handle 192kHz and greater though.
All the best"
Despite the evidence that 192kHz is being supported by other users of Head-Fi and contrary to the Qutest manual and to Chord's own website.
Since your reply said all Chord products, I went looking over the website:
Their website actually says up to 24bit 96KHz for Hugo 2. However I have never had any problem running 192KHz on my Hugo 2.
Website says 24bit 192KHz for the Mojo.
While the website says nothing on the TT2, but the manual says 192KHz on the optical input. (Manual for the previous version TT states 192KHz on optical too.)
This is all very confusing. I was solidly under the impression that the Hugo 2 and TT2 run 192KHz optical. I was under the impression that all Chord DACs run 192KHz on the optical.
I buy Chord DACS being under the impression they ran 192KHz on optical. I buy 192KHz music when I can, so I would want DACs to run that as the minimum. That's how I thought it was and never gave it a second thought.
(I don't mean to cause trouble. However the website saying a product runs up to 96KHz, and the manual saying 192KHz. That has to be illegal; it's got to be a mistake though. Someone should advise them to get that straight before it causes trouble. Although I doubt it will.
Not that I am going to say anything because my DACS all run blue, so I am assuming they are running at 192KHz when I use optical. I almost always use USB though. Me showing the Qutest running optical was time consuming. Getting the cable, plugging it in, finding 192KHz music, swapping settings over on my PC (a few times), photographing, transferring photos to PC. Writing long post.)
192/24 via optical plays nicely, blue light confirms this.
Nice to see. I was hoping someone else would confirm Qutest playing 192KHz. Since Chord are saying the Qutest runs at 96KHz, folk might have thought I was pulling a trick. What with me having posted blue on my optical input showing Qutest running 192KHz.
Your camera has done the same as mine. Shows most of the blue light as white, with just a bit of blue around it. Nice that your DAP is showing the file type information.
I believe it should be fine as long as you install the Chord native Windows driver. I don't remember any lag with the Mojo. If there were audio/video sync issues, it would be brought on this thread as Youtube is mission-critical.
I took a quick look at the AudioQuest site, did you set your Dragonfly to 'exclusive mode'?

I didn't see any native Windows driver download for Dragonfly.
The driver does not play any part in any connection other than USB. Apparent Mac computers don't need any driver at all.
